Hey guys, I made a post about a problem with my fully loaded bl. Its just not as loud as it once was and Im still having problems but ive ruled out about everything and rewired everything. Now im thinking its my amp that is the problem. Is there a way to tell if your amp isn't working properly? I can't figure out how to tell i took off the faceplate and didnt see anything and it still turns on just fine. My only concern is i backed into a truck and so my trunk is slightly bent up a little bit making the seal not very affective causing my amp to get frost on it when i put my back seat up at night. Is there any way to really be able to tell if my amp is having a problem? Im…

Curious as to what would get louder. Figure the 2 SSD's would get louder but I have always wanted a BTL. I have tons of space in my man van to use, if I remember, roughly 40 ish cubes for a box. Subs would be powered off a Crescendo 3k. My current electrical system is a stock 90 amp alt, which will be replaced with a 270 amp alt. Have a kinetik HC1400 for the front and a HC2400 for the back, probably pick up another HC2400. So, roughly with that information, and lets say that the BTL and the SSD's are in boxes tuned to 32ish hz, in there ideal space how much louder would the 2 15"s be? Thanks, Luke.

Ok, Im no expert but this is the first time seeing this piece in any subwoofer. I have an Fi Q 12 (2010 Version). I took my box out today for some room for a road trip and i come upon this piece inside the subwoofer box. I have the Pics link here. Its round about 1" in diameter. I wont be here at all for the weekend but will try to get back here to figure this piece out. plastic pictures by vietboi5o4 - Photobucket

I know this is WAY out the question, but I would love to see some of Scott's prototypes. I bet their has been some cool looking stuff that just didn't make it to production. Maybe we can get a little peak of some? I could totally understand if its not possible. But maybe some older stuff that doesn't really matter anymore.

My friend has two SI MAG 12's and the same amp as I do, my question is, which sub are the mags more comperable to in output, the BL or the BTL (Both fully loaded) So would I have to go with the 2 BTL's to be louder or would the BL's match the mags? Thanks for the help =]

so heres the deal, i have a 15" powered woofer in my apt hooked up to my pioneer ELITE 7.1 receiver, here are some of the specs, powered by a built in (Bob Carver) 500 rms sunfire amp Specifications ( Brand) Acoustic Research (model) ARS500 Driver Complement High power handling 15" Woofer (110oz magnet) Frequency Response 18Hz-120Hz±2.5dB Crossover Frequency 50Hz(24dB/Oct.)~120Hz(36dB/Oct.) Continuously Variable Rated System Power 500 Watts RMS Enclosure Dimensions 18 1/4" x 17 3/4" x 24" this woofer still sounds good but after years of abuse i have been wanting to replace it but dident know what would work with the built in amp if anything from F.I., was maybe thinkin…

Just some pics from Tom's shop he wanted me to post....Running 6 BL 18's and 6 Crossfire 4000d's...many many more to come for finals!!! hmmm...wooood Little bitta wall space Hmm...could that be a bandpass?!?! Beginnings of the amp rack... More to come~!!!!

I was just bored in class and a couple things popped into my head that i want some opinion on...i'm a class A noob and i just bought a 15" BTL..anyways i plan on running the sub off a jl 250/1 for the time being until i have enough money to buy a rockford t2k..i know it'll be underpowered as hell but i don't see anything wrong with it lol (i know the gain can't be cranked up so it clips and all don't worry)..but the underpowered sub will still be better than my door speakers that i listen to now since my sub went bye bye haha don't ask.. anyways i'm tight on money being that i'm still a teenager and all .. but nevermind all that sry i just i know there are some expirience…

So I just recieved my BL 15" fully loaded last week i got it pretty much broken in and today i noticed my box had slid around in my trunk almost sliding its way into my back seat and since my back seats were folded down the rubber rib of the sub actually got wedged against the ceiling of my trunk which is about 3-4 inches shorter towards the opening then in the middle of my trunk where it normally should sit. I tried my best to carefully get it out but i failed and ripped about a 2-2.5 inch slit in the rubber rib( bassically it looks like someone took a razor blade to it). I listened to it and theres no difference in sound or SQ that me or anyone could notice. Im wonderi…

hey guys..i will just get straight to the point..... Is 4.4 cubic for a fi bl 15'' too much??? It has the P_Chamfer opt only... dual 1 ohm will be wired to 2 ohms on a MTX TA81001... oh and its tuned to 31.16 using re box calculator

I'm looking to buy some speakers but i'm a little stuck i'm looking at either one 15 BTL or 2 15 BL's. The thing is i really want to know which would be louder as far as bass and quality? What kind of setup should I use? I'm about to buy me a 2000- 2005 impala ls 3.8 v6 125amp alt. With the two Bls would i need to get a h.o. alt or would i be ok with just 1 optima yellow top in the trunk and a battery under the hood, of course the big 3 is going to be done but will 4 gauge wire be enough. also this is a daily system that i'm setting up I'm going to get 1 1500 watt brutus mono amp for now. a little help from everyone will be great thanks.

I have money to order a Sub finally. I always seen videos of people fi btls breaking every part of their car. My friend has a JL audio w7 2x 12". Im looking to go bigger and better. Although upon purchasing a FI BTL , there are so many types and ' add-ons +$'. I dont know what to get I want 1x Fi Btl 15" in a 2002 Ford Taurus SES. Anyhelp? What amp? Anything?

here are some pics of the install, we still need to wire up the battery and ground the amps. heres what in it: kenwood ddx-6017, fully loaded 15" fi BTL, ma audio hk4000d modded to 1 ohm stable, ma audio hk398, 6.5" alpine type x componants in the front and no rear fill, theres going to be 2 yellow tops under the hood, 200A HO alt, and big 3 with 1/0ga. http://i40.photobucket.com/albums/e215/mos..._25_07_2022.jpg http://i40.photobucket.com/albums/e215/mos..._25_07_2021.jpg http://i40.photobucket.com/albums/e215/mos..._25_07_2020.jpg

Right now im rocking a 1x fi q 12" in a 2.5 @ 30hz box, it gets pretty loud, but i feel i have to strain a little to get it to my likings. I want to upgrade and have a few optinos that im asking you about I plan on buying a second sae - 1000D and strapping them and producing 1800 - 1900 @ 2 ohms. So that what i have to work with. Here are my options that im intrested in. I have a LSQ oriented system as you can see in my sig Option 1- buy another fi 12 q and sealing both of them each in a 1.3 sealed box or both of them in a 2.5 sealed box. I could build an amp rack Option 2- buy another fi 12 q and porting them in a 5 @ 32 hz box. could not build an amp rack Option 3- i co…

Now, before anyone tells me to read about the options on the Fi site, I'm just letting everyone know I did that. So know that I got that out there, I'm putting a 15 BL in a '93 Saturn SW2 in 4.35cuft@32Hz, and I was wondering what options would be best for me? I will be using this setup for daily driving and I listen to ALL types of music. Right now, I would be feeding this thing 600 watts, but will definitely upgrade to 1000+ in the future. I'm thinking that I will get the cooling upgrade for sure, but I wasn't sure about the flatwind coils. The reason I say this is because I'll be using 8 gauge speaker wire and was wondering if that will fit in the normal coils with…

So I am trying to decide between either a Q or a BL. I will be picking up either a 12 or a 15, depending on what kind of car I finally decide to get (is it sad that size of the trunk to fit a bigger box is actually a big factor in my decision?). So I am looking for something clean, but powerful. I listen mostly to rap, but I like to mix it up with some rock every now and again. One of the big problems I have with my current setup is that my subs can't seem to keep up with a quick bass line. So I am looking for something quick, yet powerful enough to feed my need. Now I understand the BL will get louder than the Q but at the loss of SQ. How much of a loss are we talking ab…

I have 4 Q15's ported in 10ft^3 tuned to 32hz on a IA40.1 @ .5 ohms. I am hitting 152db on a TL and 159.6db on AC mics, but I have it tuned for music and I feel the Q's are much more powerful down low. I compete locally for fun in unsanctioned events and have a nice lil collection of trophies. So this past Sunday, a local but large Car Club asked me to join up, because they want an SPL division for SBN and whatnot, and they have and audio shop on board to help with builds. So I agreed, but know that I need to do better then 152 on a TL to have a chance in an "official" comp. I have only a 140 amp alt, but I have 2 batts for my electrical and the IA 40.1. Max box ~10cube…

Im trying to see which sub is a good "SQL" sub. I had a 10w7 in a ported box and it rocked. Im looking to put 2 10's in my nissan titan in a ported box, its gonna have about 1.3 cu ft for each chamber, powered by a sundown 2000d.

Heres a quick vid of my BTL's gettin down on 2 hifonics colossus XX II amps in a cut through in a rear loading horn hybrid designed by Pete... Im going to be replacing the 12's with the new 15's next week and gettin a new box design from Pete Kulicki This should work [url="http://s251.photobucket.com/albums/gg317/thumpster_18/?action=view

I just had my highs and mids installed in the truck and now need a little low end. After getting my first pair of Q's from Fi, I'm a dedicated customer. BTW, they are still going strong, now in my cousin's Explorer. Anyway, my current setup is as follows: 2 Focal 165 KF 2 Focal 165CVX JL 450/4 I'm looking to get something that I can hide under the back seat. Here's what I was thinking: 1 10" SSD RF T500-1bd in this pre-fabbed box CRB07-110/112 LINK: http://www.subthump.com/crb07.htm it's the one at the bottom of the page One concern, magnets must be no more than 6.25" in diameter...will that be an issue with the SSD? I'm a firm believer in building my own boxes, but w…

Alright guys ive read many of the forums on here and i have a pretty good idea on what im getting. But there is a lot of stuff im confused on..Here is what i know i am getting for sure: FI BL 15 inch sub Refurbished Sundown 1500D amp from www.db-r.com Wiring:http://www.knukonceptz.com/productDetail.cfm?prodID=KLM-AK0 KLM 1/0 Amplifier Installation Kit (60A fuse type) ( Is this the right wiring i should get? I saw people say to get the 1/0) Now this is where i get confused... Box- i know i want a ported box, i was going to get my friend to make it. He has experiance making boxes..Or should i get a professional place to do it ( costs way more money though) these were the…

Well guys, thought you might want to see what I got in the car finally. After a LOT of hard work (totally dynamatted the car, custom mounted Utopia tweets in the front, etc etc) I got the subs in today and started hittin on em w/ the Fosgate T20001bd. Here's a quick pic after I got the subs in. The box is 2.25 cubic ft. per sub, tuned to 32Hz. It's not the Cadillac of Meade's, lol but it'll do for me. btw, props to Fi, Scott, Nick, everybody on the "team." I played the subs for about 15 minutes and I'm ready to go jam em tomorrow hehe.

i ordered two fi btl n2 15's and i was meaning to order 18's..i ordered em sunday. any suggestions on getting this resolved?
